Each of these die-blocks has a groove for each tool or tool-section which is to be active, said groove extending through the edge of the block to a tool-locating recess. Still another feature of the invention concerns the positioning of the tools with reference to the die-block. Each tool is arranged to reciprocate upon a carrier having a portion directly oo-operating with the dieblock and movable toward and from said dieblock and angularly with respect thereto. The carrier may thus adapt itself to readily enter the die-block-groove which is to direct it intothe operating position. As herein disclosed, the carrier is in two portions, a slidable primary portion and a secondary portion pivoted upon. said primary portion. Upon the secondary. portion the awland driver-holder is mounted, the movement of this holder alining either of the tools with the corresponding die-block-passage. To cause the movement of the carriers with respect to the die-block, I preferably furnish means for shifting all the carriers simultaneously, as by a movable cam-plate, and there is also preferably associated with the carriers a guide which retains the secondary portions in a definite angular relation after they have left the die-blockgrooves, so they will be correctly located to reenter said grooves. The die-block, as herein i1- lustrated, is furnished with means, as a spring, forholding itabove its operating position. In this relation, the tool-carrier may enter the dieblock-grooves and be alined with the terminal recesses. Then, upon lowering the block, the recesses receive and retain the operating sections selected by the particular block, while lockingmeans holdsthe block for the fastening inserting operation. In its broader aspect, the selective positioning of operating sections under the control of interchangeable die-blocks is not a part of. my invention, it being. disclosed and claimed in the applicationf-or Letters Patent of the United States, filed on October 15, 1931, in the name of Fred. L. MacKenzie and bearing the Serial No. 568,969.

An additional feature of the invention has to do. with a novel arrangement for supplying the fastenings for insertion by the mechanism or mechanisms previously referred to. When there is a plurality of sections for inserting fastenings,

a fastening-supplying means is carried by each section, this fastening-supplying means, in the present instance, being made up of feeding and cutting and transferring mechanisms. When the section includes a carrier and an awl-. and

driver-holder movable thereon to bring either of these tools into operating position, I preferably provide connections to the holder-moving means.

for actuating the cutting and transferring mechanism. Thus, a fastening, ready for. insertion,

may be fed conveniently to the inserting mecha means wherebythe feeding means is caused to advance the material to an extent dependent upon the penetration of the workby the corre-' sponding awl. Each inserting means is thereby suppliedwitha fastening of thelength'best suitedto the conditions it encounters in the heel-seat,

regardless of the associated inserting means.

Thisindependence is best obtained through yieldable operating connections, which connections may include a fluid. With each awl is associated what is herein disclosed as a reciprocatory actuating member, and I may cause this actuating member to move into engagement with operating connections for the fastening-supplying means, this resulting in their action in accordance with the length of travel of the awl and the thickness of the material pricked by said awl. When each complete fastening-inserting means includes both an awl and a driver, and, as the actuating member is common to both, there is included means for causing said actuating member to effeet the operating connections for the fasteningsupplying means only upon the operation of one of the tools, as the awl. This is accomplished by connections to means for moving tools into op erating relation to their actuating member, said connections rendering the operating connections for other tools ineffective.

Other features of the invention will become obvious upon consideration of the following description and the appended claims. In the accom panying drawings,

Movablevertically' in the cross-bar is a plunger lfihaving. pivoted upon its lower extremity for. movement into. and out of operating position a Work-supporter jack-post 18, shown in Fig. 2 of. the drawingsas arranged to receive a lasted shoe S.. As. is customary. in apparatus of this character, pressure is. applied to the work in preparationfor. the inserting. operation, this being made up. of. a preliminary or measuring pressure and a finalor clamping pressure. In. the present instance, this effect is obtained by movement of the jack-postby such means as is indicated at M in. Fig. 2 and. fully disclosed in Letters Patent of the United States No. 1,847,274, Standish,

March 1,. 1932; Since thispressure mechanism is not directly ooncernedwith the present invention, it will-notbedescribed, beyond the statement that it: employs a fluid connecting medium, as oil, containedwithinthe plunger 16, which is hollow, and that preliminary pressure is applied through connections ;,ioined to a startingtreadle 22 fulcrumed at the bottom ofthe frame 10, while final pressure is transmitted through connections 24 from.a.cam.26 carried by a main actuating shaft 28 journaledhorizontallynear the lower portion ofthe frame.

Supportedupon the frame below the jack-post 18 is abracket 30 (Figs. 2, 5-and 6) containing a verticalbore 32-furnishing a socket to receive a spindle 34 depending from'the under side of some one ofa set of die-blocks 36, there being in the set a block for each-.fastening-design which is to be employed. The angular relation of each dieblock, with-respect torotation-about the axis of its spindle, is fixed in the operating position by a pin 37 which enters an opening in the top of the bracket adjacent to the bore 32. Near the periphery of the block is a series of upwardly and inwardly inclined passages 38, corresponding to the location of the fastenings of the particular design to which said block corresponds. The lower portion of each passage has a frusto-conical enlargement or recess 40 (Fig. 5), from which opens outwardly through the edge of the block a groove 42, which nowhere emerges through the upper block-surface with which the work contacts. Between the spindle 34 of each block and the bottom of the socket 32 is a compressionspring 44 of such dimensions that the dieblock, the spindle of which is inserted in the socket and not finally secured in place, is elevated somewhat above the top of the bracket 30. In the normal or operating position, the spring is compressed, so the under side of the block rests upon the bracket, being secured in this position by a rotatable latch 46. The reasons for thus forming and supporting the die-block will later be made clear. When the jack-post 18 is swung in from the forwardly inclined work-receiving position to its vertical operating position, the heel-seat of the advanced shoe is alined with the die-block, ready for the insertion of the seat-securing fastenings after pressure has been applied by the mechanism M. The central work-engaging portion of the die-block, as best seen in Fig. 5, is preferably provided with a concavity so formed that, under the applied pressure, the heel-seat, which is in temper, will be molded to substantially fit the concave end of the heel to be attached. To correctly locate the jacked work for co-operation with the particular nailing design contained in the dieblock employed, this design varying with the size and style of shoe being operated upon, a backstop may he provided. This, as appears in Figs. 1 and 6, consists of a fork 48 arranged for engagement with the counter-portion of the jacked shoe. The fork depends from a slide or carrier 50 movable horizontally upon a bar 52 extending toward the jack-post from a bracket 54 rising from the frame. Secured horizontally at one side of the slide is a tubular spindle 53, upon which a vertical sector 56 is clamped for angular adjustment about the spindle by a split hub 55. Upon the periphery of the sector appears a series of graduations 57 (Fig. 1), with which is associated an index-plate 59 secured upon the slide 50. Within the spindle is rotatable a short horizontal shaft 58. The shaft has at one extremity a crank-handle 60 carrying a spring actuated latch 62, which may be caused to engage any one of a series of openings or retaining devices 64 about the sector (Fig. 6). Also fast upon the shaft 58 is a pinion 66 meshing with a rack 68 formed upon the upper face of the bar 52. When the operator has selected the die-block 36 to be utilized for the particular work into which the fastenings are to be driven, he moves the crank 60 to a point at which it is secured by its latch 62 in the opening 64 corresponding to the size of the shoe. This brings the fork 48 into the correct position to so locate the jacked shoe over the die-block that the openings in said die-block will be symmetrically related to the periphery of the insole. This setting, however, may be modified by adjustment of the sector 56 about the spindle 53, this giving a further adjustment taking into account the peculiar form or style of the work. As the crank, sector and all the associated stop-adjusting elements are movable with the slide 50, they may readily be moved rearwardly by rotating the crank, thus leaving ample space for changing the die-blocks.

For each different inserting position for the fastenings to be driven into the heel-seats of the entire range of sizes of shoes to be operated upon, a heel-seat-pricking, fastening-measuring and feeding and fastening-inserting section A (Fig. 5) is movably mounted upon the frame 10. These operating sections may be identical in their arrangement and but one will be described in detail. As illustrated, each section has a primary carrier '70 provided with arms 72, '72 movable in horizontal ways in the frame. Arranged to turn about a vertical pivot-rod '74 at the inner extremities of the arms is a secondary carrier '76, which has spaced side-plates '78, '78. Mounted upon the tops of these side-plates is a mechanism B for supplying the fastenings to be inserted. The lower portion of the frame of this mechanism B has an extension 80, from which rises a frustoconical projection 82 formed to fit within the recessed portion 40 of the die-block-passage 38, and having a passage 84 to register with said passage 38 of the die-block. These openings 84 and 38 furnish a throat through which the pricking and fastening-driving operations occur. The fastening-material P may consist of wire or cord, the latter being of such a fibrous substance as paper, carried upon a reel 86 for each operating section A, the reels being shown (Fig. 1) as arranged in two groups above and outside the sections. The flanges of each group of reels may rest upon spaced rolls 88, 88 rotatable in end-plates 90 secured to the frame. At the axis of each reel is an opening through which passes a loosely fitting rod 92 supported by the end-plates and retaining the reels against accidental displacement. The rod is readily separable from the end-plates to facilitate the replacement of empty reels. From each reel the fastening-material is led between a lower feed-roll 94, journaled in the frame of the corresponding mechanism B, and an upper pressure-roll 96 rotatable upon a pivoted arm 98 and urged toward the companion roll by a spring. 100. The roll 94 is rotated to advance the fasteningmaterial by a lever 102, upon which is formed a segment 104 meshing with an idle pinion 106, which pinion, in turn, engages a segment 108 arranged to turn adjacent to the roll 94 and having a one-way connection 109 thereto. A spring 110 draws the lever 102 into contact with an actuating rod 112 movable through the pivot-rod 74, which is tubular. The oscillation of the lever 102, as a result of the elevation of the rod 112 by the workpricking mechanism, as will shortly by described, turns the feed-roll 94 to advance the fasteningmaterial to a definite extent dependent upon the thickness of the heel-seat-stock. The fasteningmaterial thus fed passes down a passage 114 and through a passage 116 in a sliding cutting and transferring member 118 mounted to reciprocate in horizontal ways near the bottom of the mechanism B. In its movement, the slide 118 carries its passage 116 from alinement with the passage 114 into registration with the throat 84, 38. After the fastening-material has been fed into the passage 116, the slide is reciprocated and the fastening cut to the proper length, dropping upon a yieldable retaining member 124, which temporarily holds the fastening in the passage 116. The manner of actuation of the slide will be developed in connection with the description of the pricking and driving mechanism.

Fulcrumed between the side-plates '78 of each v the die-blocks 36.

operating section A is an upper bell-crank-lever 126 and a lower bell-crank-lever 128. Engaging the upper lever by a hook 130 and the lower lever by a depression 132, and carried by these levers to be moved outwardly and inwardly between the plates 78 by what approximates a parallel motion, is a holder 134 containing two passages inclined at substantially the angle of the passages 38, 84 and 116. This inclination is such that the openings are pricked in the heel-seat and the fastenings driven through said openings substantially normal to the curvature of the last-plate, though this inclination may be somewhat in creased to insure clinching of the fastenings inwardly. In the inner passage of the holder, an awl 136 is arranged to reciprocate, while the outer passage contains a reciprocatory fasteningdriver 138. The shank of each of these members terminates in a ball 140. Normally, or at the beginning of an operating cycle, the ball of the awl 136 rests within a cylindrical recess 141 in the upper extremity of an actuating bar 142 arranged to reciprocate in a guide member 144 secured between the side-plates 78. An end-portion 146 of the bar overhanging the ball holds the latter against longitudinal displacement. At the same time, the ball of the driver 138 is locked against movement, and held in alinement with the barrecess 141 ready to enter it, by resting within a recess 148 in the guide 144. When the ball of the driver is engaged by the bar 142, the awl is locked by a recess 150 in the guide at the opposite side of the bar.

As illustrated in Fig. 5, the holder 134 is positioned with the awl 136 alined with the throat 84, 38 ready for the pricking of the work held against the die-block 36. Simultaneously, the fasteningmaterial P of each section A in use is fed from its reel 86 ready for cutting. At the lower extremity of each actuating bar 142 is formed a cylinder 152, in which operates a piston 154 pivotally connected to a floating lever 155, one end of which may be shifted along a horizontal passage 156 in the frame as the carrier '70 is moved in changing This latter operation will be hereinafter more fully described. The other end of the lever is received between horizontal cheeks 158 at the top of a vertically reciprocatory plunger 160 guided within a bracket 162 secured to the frame. At the bottom of the plunger is a roll 164 (Figs. 2 and 3) entering a cam-groove in a disk 166 fast on the shaft 28. Power may be applied to this shaft through a pulley 1'70 and a singlerotation clutch 172 (Fig. '7) governed by the treadle 22 upon its full depression. As already indicated, when the sections are drawn out for changing the die-block, each lever 155 will be moved outwardly, its end traveling in the passage 156. At this time, it will leave its position between the cheeks 158, and for its support I have provided a curved rail 1'74 carried by the frame and which guides the end of the lever back between the cheeks upon restoration or" the parts to their operating positions. The piston 154 has an axial passage 176 joined by a flexible tube or conduit 178 to a horizontal curved pipe 180, this being piped at 182 (Figs. 3 and '7) through a valve-casing 184 into a by-pass 186 opening into the opposite extremities of a cylinder 188 belonging to a pump D and supported on the frame. The piston 190 of this pump is continuously reciprocated by driving connections 192 to the shaft 28 to create a pressure upon the oil or other transmitting fluid in the system, this being sufficient toforce the awls through heel-seat material of maximum resistance to the plate of the last Within the shoe. In the by-pass 186 is a relief-valve 194- extending into a casing 196 and held upon its seat by a spring 198. The pump-pressure is delivered through a check-valve 200, the lower portion of the by-p'ass, a passage 202 in a valveplunger 204 movable in the casing 184 and held normally open by a spring 206, the piping 184 and the curved pipe 180, where it divides and passes through the flexible tubes 178 to act simultaneously in all the cylinders 152, thus holding said cylinders against downward movement while the cam 166 is acting to force up the levers 155. The awls of the holders 134 which are locked in operating position by the die-block 36 are thereby caused to penetrate the heel-seat of the jacked shoe through the throat 84, 38. When the awls strike the last-plate, the resistance causes the valve 194 to yield under the influence of the pump-pressure, opening the by-pass. The pressure is consequently relieved by circulation through the by-pass, and any further movement of the levers 155 merely raises the pistons 154 idly in their cylinders. The amount of pressure exerted by the awls may be varied simultaneously for the set which is in use by adjustment of an abutment-screw 208 for the spring 198. This causes the spring to offer such a resistance that the valve will not open the by-pass until ample force has been exerted to drive the awls through the work, yet without enough pressure to mutilate the last-plate.

It will be obvious that the distance which an awl travels after emerging from its die-blockpassage until it strikes the last-plate will be equal to the thickness of the heel-seat-material pricked, and that movement of the actuating bar 142 and its cylinder 152 will be stopped at substantially the same time as the awl. This relation is utilized to determine the correct length of the fastening-material P which is to be cut for driving into the pricked opening. The lower extremity of the actuating rod 112 for each fastening-supplying mechanism B has a shoulder 210, which, at the time of pricking, lies above the inner portion of a fork at the end of an arm 212 pivoted upon a three-armed lever 214 fulcrumed at 216 upon a depending portion 218 of each section A. The arm 212 is limited in its downward movement uponits pivot by a boss projecting from the lever 214 and upon which it rests. On the exterior of the corresponding cylinder 152, below inner rounded ends of the arm 212, is a projection 220. The distance between the projection an arm is such that, after the awl has reached the heel-seat-material, they will travel in contact, the arm being moved by the projection a distance proportionate to the thickness of the heel-seat-material. The resulting movement of the rod 112 by the arm is transmitted through the lever 102- and gearing 104, 106, 108, which is so designed that the material P is fed forward by the roll 94 an amount somewhat greater than the thickness of the heel-seat-material, to allow it to be properly upset or clinched. Since the upward travel of the projection 220 varies with the thickness of the work, it is thus automatically measured, and the fastening-material fed in accordance with such measurement.

At the termination of the pricking stroke of the awls, the cam 166 causes them to be withdrawn with the actuating bar 142 to the initial positions. The retraction of each bar when its lever 155 is moved down may be made certain by contact of shoulders at 221 (Fig. 5) upon the cyleffected in two ways.

inder 152 and piston 154. This again alines the ball-receiving recess 141 with the locking recesses 148 and 150 of the member 144. Now a driver 138 is to be brought into operating position in place of each awl 136.

The material P having been fed, the corresponding slide 118 reciprocates to sever and then deliver a fastening for insertion in the pricked opening. The plunger 160 contains a vertical recess, in which is guided a second plunger 222 carrying a roll 224 (Fig. 2). This roll lies within a cam-groove in a disk 226 secured to the shaft 28 and acting to reciprocate the plunger 222 in the desired time-relation. Between horizontal cheeks 228 secured to the upper extremity of the plunger 222 projects, for each operating section A, the end of a lever 230 fulcrumed upon a depending portion of the guide member 144. A link 232 joins the lever 230 to the bell-crank-lever 128, the latter lever being, in turn, connected by a link 234 to the bell-crank-lever 126. Movement of the lever 230 by the cam 226 at the completion of the pricking operation, through the links rocks the bell-crank-levers in a clockwise direction (Fig. 5), carrying the holder 134 to the right to shift the awl out of alinement with the throat 84, 38 and bringing the driver 138 into operating position. The ball-end 140 of the awl is now locked against longitudinal movement in the recess 150, while that of the driver occupies the actuating bar-recess 141. At the beginning of the movement of lever 126, a cam-surface 236 upon it engages the lower extremity of a lever 238 fulcrumed between the side-plates '78. The upper end of the lever 238 has threaded horizontally through it a contact-screw 240 engaging the slide 118 to move it across the end of the passage 114. The slide-opening 116 is thus carried quickly and with considerable force out of registration with the passage 114, severing a fastening from the material P, which has been advanced through a measured distance, as already described. At first, the end of an arm 242 of lever 126 moves idly in a space 244 in the slide 118, but after the fastening has been cut and has fallen upon the retaining member 124, this arm contacts with the wall at the inner side of the space and moves the slide until its passage 116 is in registration with the throat 84, 38 and with the driver 138. Through a connecting link 248, the lever 230 also swings the lever 214 to carry the fastening-advancing arm 212 out of active co-operation with the rod 112, so there shall be no feed of the fasteningmaterial during the driving movement of the actuating bar 142.

With the elements positioned as above indicated, the piston 154 and the cylinder 152 of each active section A are connected unyieldingly for the operation of the driver 138. This may be Fixed to the shaft 28 is a cam 250, with which contacts one arm of a bellcrank-lever 252 fulcrumed upon the frame (Fig. '7). The other arm of the lever is joined to the stem 254 of the normally open valve 204. In

1 preparation for the fastening-driving, the cam moves the lever to close the valve against the force of the spring 206. The pump-pressure is thus cut off from the piping 182. The valve 194 opens and the fluid circulates idly through the by-pass. On account of the substantially non-compressible character of the oil or other fluid, the cylinder and piston will act as a rigid unit, the resistance encountered by the driver 138 being insufficient to move them relatively, and the cam 166 causes the lever 155 to reciprocate the driver. This,

entering the passage 116, displaces the retaining member 124 and forces the fastening which was held by the member through the now alined passages 116, 82 and 38 into the opening pricked by the awl 136. If it is desired to join the piston 154 to the cylinder 152 positively, rather than by the locked body of fluid, there may be formed upon the cylinder a shoulder 2.56 into engagement with which may be carried a shoulder 258 upon a lever 280 fulcrumed upon the mounting of the piston. The lever 260 has a roll 262 running in a slot 263 in an actuating member 264 hung upon a depending arm of the lever 214 and upon a link 266 pivoted upon another arm. When the link 248 turns the lever 214 anti-c1ockwise (Fig. 5) to prevent fastening-feeding action by the arm 212 during fastening-driving, it also carries the actuating member 264 to the right and the levershoulder 258 beneath the cylinder-shoulder 256. Therefore, the piston 154 is directly coupled through the lever 260 to the cylinder 152, without regard to the contained fluid, the travel of the roll 262 along the slot 263 permitting the continuing engagement of the shoulders during the driving stroke. When the coupling-lever 260 is not employed, it, with the member 264, may be removed from the machine. When it is in use, the fluid connecting means may act to cushion the initial contact between the shoulders 256 and 258.

To allow the die-blocks 36 to be changed conveniently, so the fastenings may be inserted in accordance with one or another of the varying designs, the apparatus has means for moving all the inserting sections A simultaneously. Each primary carrier '76 has formed upon its arms '72, '72 racks 2'70 meshing with pinions 2'72 upon a vertical shaft 2'74 journaled in the frame. A torsion-spring 2'76 surrounds the shaft and is secured thereto and to the frame, acting to so ro-- tate the shaft as to carry the section A toward the die-block. Adjustably secured to each carrier '70 is a roll 2'78 (Fig. 1), which may be engaged by one of a series of cam-projections 280 from a generally segmental plate 282 guided to slide:

on the frame. Near one extremity of the plate is formed a rack 284, with which meshes a pinion 286 fast upon a vertical shaft 288 turning in the frame and which has at its upper end a handcrank 290. Rotation of the crank anticlockwise shifts the plate 282 to urge the cam inclines of the projections 280 against the rolls 2'7 8, and thereby force all the carriers of the sections out to remove the projections 82 from beneath the die-block and temporarily hold them for the die-changing operation. To retain the secondary carriers '76 at such angles about their pivots '74 that they will enter the grooves 42 in the die-block to which they correspond upon release by the plate 282, outward projections 292 from the side-plates 78 are received by depressions294 in a generally segmental plate 296 secured to the top of the frame. Each depression at its inner open end has oppositely curved and outwardly converging walls 298, 298, which'engage the projections 292 and guide these into contact with substantially parallel walls 300, 300, into which the walls 298, merge. The walls 300 are so spaced from each other that each section is admitted between them without much clearance and is thus heldin the correct relation for again co-operating with the die-block-groove to' After a section is freed from' ferences in angular relation between the ways in which move the carrier-arms '72. and the grooves 42 will be compensated for. The changing of the die-block is accomplished as follows: With the sections A withdrawn, the spindle 34 of the desired block is inserted in its socket 32 and left supported by its spring 44 above the operating po,

sition The crank 290 is then rotated to free the sections from the cam-projections and permit the springs 276 to move said sections inwardly. When the the die-block is thus raised by its spring, the projections 82 of the sections which are to be used are free to enter the grooves 42 and locate themselves below the die-block-recesses 40. The sections which are to be inactive are held out by contact of the projections 82 with the solid or ungrooved portion of the die-block. Now the block is pressed down against the elevating force of the spring 44 and secured by the latch 46. This seats all the projections of the active sections in the block-recesses, locking them in their operating positions. The edge of the descending block moves over the other sections, which remain locked out in their inactive positions. When a change is to be again made, the die-block in use is lifted from the securing projections 82, releasing those sections which have been in use. The crank 290 is turned to retract the sections, and the substitution of' the blocks made as before.

To briefly outline the general operation of the machine, all the operating sections A being forced by the cam-plate 282 away from the dieblock-receiving position upon the bracket 30, a block 36, having its passages 38 and grooves 42 corresponding to the fastening-inserting design which is appropriate for the size and style of shoe being operated upon, is placed upon the bracket, being left temporarily supported by the spring 44. Then the plate 282 is moved by the crank 290 to release all the sections. The projections 82 of those sections which are to be active in the insertion of the fastenings will there- .upon enter the block-grooves 42 under the influence of the springs 276, which, by their action upon the primary carriers '70 of the sections, move all of said sections inwardly until the selected projections 82 register with the blockrecesses 40. The correct entrance of the projections 82 into the block-grooves was assured by the positioning of the pivoted secondary sections 76 under the influence of the depressions in the plate 296 when the sections were drawn back by the plate 282. The sections A which are not to be used are maintained inactive by the engagement of their projections 82 with the solid periphery of the block. This relation having been attained, the operator presses down the block against the spring 44 and secures it by the latch 46, thus locking the chosen sections in operating position by the seating of the projections 82 in the recesses 40. The back-stop 48, which was withdrawn during the change of the die-blocks, is adjusted under the control of the crank and the divided hub 55, so the size and style of shoe being operated upon will be correctly located by the back-stop over the dieblock. A shoe, the heel-seat of which is to be secured, is placed upon the jack-post 18 while i this is swung forward, and then the post is brought to a vertical position above the die block. The operator may now depress the treadle 22, lowering the jacked shoe into contact with the die-block. The work being located by the back-stop 48, continued movement of the treadle trips the clutch 172, and the automatic operation of the machine begins. The mechanism M lowers the jack-post and applies final pressure to the work, the heel-seat-surface of the outsole being molded to the desired form by its pressure against the concave surface of the die-block, in which there are no openings, other than those of the fastening-passages 38, to deform the heelseat. The plunger 222 initially maintains the levers 230 of all the sections A with the awls 136 registering with the projection-passages 84 and the die-block-passages 38 and said awls in alinement with the actuating bars 142 held by the recesses 141, while the drivers are maintained against movement in the guide-recesses 148. The plunger 160 is raised by the cam-disk 166 and, through the levers 155, forces the awls through the throat 84, 38 and through the heelseat-material of the jacked shoe. The ends of the awls arriving at the last-plate, the co-operating cylinder 152 and piston 154 in the actuating connections for each previously rigid bar 142 yield, since the resistance to advance of the awls is now greater than the force exerted by the spring 198 to keep the valve 194 seated, so the by-pass 186 is opened. When the valve 194 leaves its seat upon the stopping of the awls by the last-plate, the force of the pump is absorbed by the by-pass, and the awls are relieved of undue pressure before the last-plate will have been indented by their action. As each actuating bar 142 rises in the pricking stroke, the projection 2220 upon it strikes the arm 212 and, through the rod 112 and connections actuated thereby, draws from the corresponding reel 86 a length of fastening-material P proportionate to the travel of the awl in the work, and feeds this into the passage 116 in the slide 118. After this pricking stroke of the awls, they are withdrawn by the descent of the plunger 160, and

the plunger 222, which up to this time has been stationary, is lowered by the cam-disk 226. Through the connections to the levers 230, all the holders 134 are shifted to carry the awls to their idle positions, locked by the recesses 150, and to bring the drivers 138 into operating relation in alinement with the throat 84, 38 and the bars 142. At the same time, connections which are actuated simultaneously with those for moving each holder 134 reciprocate the cutterslide 118 to sever the measured fastening, and then advance said slide to aline with the fastening-inserting throat its passage containing this cut fastening supported upon the retainer 124. While the fastening is thus held, the plunger 160 is again caused by its cam-disk 166 to elevate' the actuating bars 142 and compel the drivers 138 to insert the fastenings in the previously pricked openings. In preparation for this and to render the driving force positive, the actuating connections are made non-yieldable, as by closing the valves 204 to cut off connection to the spring-seated valve 194, or by coupling two relatively movable portions of each actuating bar 142 by the lever 260, or both, according to the choice of the operator. The valve 204 is closed by the cam 250, and the coupling-lever brought into play by connections to the corresponding lever 230. This connection to the lever 230 is also utilized to render ineffective the movement of the arm 212, which previously fed the fastening-material from each reel 84, the fastenings being supplied only upon the pricking stroke.
